Two women who were with San Francisco 49ers wide receiver Michael Crabtree and an alleged assault victim in a hotel room after a playoff game have told police investigators that he didn’t attack anyone.

San Francisco police are investigating the sexual-assault allegations at a party that took place after the 49ers defeated the Green Bay Packers in an NFC divisional round game on Jan. 12.

No physical evidence has been found and police have yet to determine whether the woman who said she was attacked sought medical treatment, according to the San Francisco Chronicle.

Crabtree has denied any wrongdoing and cooperated in the investigation, the Chronicle reported.

Police Chief Greg Suhr told the Chronicle that he looked for the investigation to conclude within the next 10 days.

Crabtree had six catches for 57 yards last Sunday in a 28-24 victory over Atlanta that sent the 49ers to the Super Bowl.
